How to Make Green Bean Casserole from Scratch

A traditional American side dish, green bean casserole is typically served at holiday parties, particularly Thanksgiving. In order to create a pleasing contrast of textures, the dish usually has crispy fried onions on top of green beans & mushroom sauce. The Campbell Soup Company created and marketed it as a recipe utilizing their cream of mushroom soup in the 1950s. Since then, it has been a standard part of holiday meals all over the United States. The dish’s versatility and flavor profile are what make it so popular.

Key Takeaways

  • Use fresh, crisp green beans for the best texture in your casserole.
  • Homemade cream of mushroom soup enhances flavor compared to canned versions.
  • Blanch green beans before baking to maintain their vibrant color and tenderness.
  • Crispy onion topping adds essential crunch and can be made from scratch or store-bought.
  • Plan ahead by assembling the casserole in advance and storing leftovers properly for convenience.

Although the classic recipe is still frequently made, many cooks alter it to suit their dietary needs or personal preferences. Changes could include using homemade mushroom sauce in place of canned soup or using different add-ins and toppings. In American home cooking, green bean casserole is a symbol of both culinary tradition and creative expression. The selection of green beans is crucial when making a great green bean casserole. Because freshness is crucial, choosing premium green beans can greatly improve the dish’s flavor and texture.

Choose beans that are firm to the touch, have a vivid color, and have no soft spots or imperfections. Young, tender green beans, also known as “haricots verts,” are preferable because they are thinner and more delicate than regular green beans. In addition to having a more sophisticated flavor, these beans cook more uniformly, maintaining their crispness even after baking.

If fresh green beans aren’t available, frozen green beans might be a good substitute. To maintain their flavor and nutrients, they are usually flash-frozen after being harvested at the height of ripeness. It’s crucial to look for any additional ingredients or sauces on the packaging when using frozen beans because these could change the intended flavor profile of the dish. Although canned green beans are an alternative, they frequently don’t have the same texture and freshness as their frozen or fresh counterparts. If you decide to use canned beans, make sure to give them a good rinse to get rid of extra sodium and enhance their flavor.

For convenience, many green bean casserole recipes call for store-bought cream of mushroom soup, but creating your own from scratch can make the dish even better. Making your own cream of mushroom soup gives you more control over the flavors and ingredients, making the sauce richer and more satisfying. For a complex flavor profile, start by choosing a variety of mushrooms, such as button mushrooms, shiitake, or cremini. The mushrooms should be sautéed in butter until they are golden brown and have lost their moisture. This process gives the soup more depth and improves its flavor. Add the minced onions and garlic to the pan after the mushrooms are cooked, letting them soften and smell.

The soup will thicken as it cooks if you then add flour to make a roux. To get a creamy consistency, gradually whisk in heavy cream or milk with vegetable or chicken broth. For extra flavor, add salt, pepper, and fresh herbs like parsley or thyme. Simmer the mixture until it reaches the thickness you want. In addition to tasting better, this homemade version avoids the artificial flavors and preservatives that are frequently present in canned soups.

Achieving a well-balanced flavor profile in your green bean casserole can be greatly impacted by the seasoning. Even though salt and pepper are fundamental ingredients, you might want to add more herbs and spices to make the dish even better. For example, a small pinch of onion or garlic powder can enhance the casserole’s savory flavors without overpowering the other ingredients. The earthiness of the mushrooms can be complemented by the aromatic quality of fresh herbs like rosemary or thyme.


Nutmeg is another fantastic seasoning that works well with creamy foods. Warmth & complexity can be added subtly with just a dash. Also, for a touch of umami that enhances the flavor overall, think about using soy or Worcestershire sauce. It’s important to taste as you season your casserole so that you can modify the flavors to suit your tastes and make sure all the ingredients work well together.

One of the key components of green bean casserole is the crispy onion topping, which contrasts with the creamy filling to provide a satisfying crunch. Although fried onions from the store are handy, preparing your own can improve this dish even more. Slice sweet onions, like Vidalia or yellow onions, thinly before making homemade crispy onions. To add flavor and help achieve a crispy texture when fried, soak the slices in buttermilk for approximately half an hour. Once the onion slices have soaked, dredge them in a flour and cornmeal mixture that has been seasoned with salt and pepper.

The topping’s texture is improved by the additional crunch that the cornmeal provides. To prevent overcrowding, carefully add the coated onion slices in batches after heating the oil in a deep skillet or fryer to 350°F (175°C). After they are crispy and golden brown, drain them on paper towels to get rid of extra oil. In addition to tasting fresher, this homemade topping lets you customize the texture and seasoning to your preference. When preparing green beans for casserole, blanching is a crucial step because it ensures that the beans cook evenly while maintaining their vivid color and crisp texture.

A large pot of salted water should be brought to a rolling boil in order to properly blanch green beans. Add the trimmed green beans to the boiling pot & cook for three to five minutes, or until they are bright green & slightly soft but still crisp. To stop the cooking process, immediately place the blanched beans in an ice bath, which is a bowl filled with ice water.

In addition to preserving their color, this method keeps them from getting mushy during the casserole baking process. Before adding the cooled beans to your casserole mixture, make sure they are completely drained. For your finished dish to have the ideal balance of crisp and tender green beans, this step is essential. When you put your green bean casserole together, all of your hard work comes together to create a cohesive dish. Preheat your oven to 350°F (175°C) so that, after assembly is finished, it is ready to bake.

Your homemade cream of mushroom soup and your blanched green beans should be combined in a big mixing bowl. Make sure the sauce is evenly distributed throughout the beans by giving them a gentle stir. After that, mix in any extra ingredients you might want to add, like cooked bacon bits for a smoky flavor or shredded cheese for extra creaminess, and then transfer everything into a baking dish that has been greased. To guarantee even cooking, evenly distribute the mixture throughout the dish. Lastly, generously cover the entire surface with your homemade crispy onion topping so that it bakes up as crunchy as possible.

Your assembled green bean casserole becomes a bubbling masterpiece that is ready to serve when it is baked. Put your casserole dish in the preheated oven & bake for 25 to 30 minutes, or until the edges are bubbling and the dish is thoroughly heated. Keep an eye on it while it bakes because the time may vary based on your oven and how hot your ingredients were when they were put together. After baking, try broiling the casserole for a further two to three minutes for an extra crispy topping. Just be careful not to burn.

Achieving a golden-brown crust on top while maintaining a warm and enticing creamy filling underneath is the aim. To help set the layers & facilitate serving, take it out of the oven after it is perfectly baked and let it cool slightly. When it comes time to serve your green bean casserole, presentation can make it much more appealing.

Spoon portions onto individual plates or serving platters using a large spoon or spatula, making sure that each serving has both the crispy topping and the beans. Consider adding freshly chopped herbs, like parsley or chives, as a garnish for a touch of elegance. This will add color and create a new contrast to the rich flavors of the casserole. You can further enhance your meal by serving your green bean casserole with complementary dishes. For example, serve it with grilled meats at summer barbecues or roasted turkey or ham at holiday get-togethers.

Its savory flavors and creamy texture make it a standout side dish on its own and versatile enough to go with a variety of main courses. The ability to prepare green bean casserole ahead of time can save time on hectic holidays or get-togethers, which is one of its many wonderful benefits. To ensure that they stay crunchy rather than soggy from moisture during storage, assemble your casserole up until baking, but wait until right before baking to add the crispy onion topping. Before baking, cover firmly with aluminum foil or plastic wrap and chill for up to 24 hours.

After serving, keep leftovers in the fridge for up to three days in an airtight container. Both an oven & a microwave can be used for reheating, but using an oven will preserve the desired crispy topping more effectively than using a microwave alone. If you’re reheating it in the oven, cover it loosely with foil until it’s heated through, then take it off for a few minutes at a higher heat to crisp it up once more. Although many people have a special place in their hearts for traditional green bean casserole, there are many variations and substitutes that can accommodate various dietary requirements and tastes.

If you want a lighter version, try substituting Greek yogurt or low-fat sour cream for heavy cream in your mushroom sauce. This will cut calories without sacrificing creaminess. There are plenty of vegetarian options as well. For example, you can make your cream of mushroom soup with vegetable broth instead of traditional chicken broth, or you can add extra vegetables to your casserole mix, like sliced bell peppers or carrots, to add color and nutrition.

If you like flavors from around the world, you might want to add ingredients like sesame oil or soy sauce for an Asian twist or spices like chili powder or cumin for a Southwestern flair. To sum up, green bean casserole is more than just a side dish; it’s a chance to express culinary creativity while honoring tradition at family get-togethers. You can make a memorable dish that will delight guests at any occasion by choosing high-quality ingredients and taking your time with each component, from fresh green beans to homemade soup.
